本科学历认证

请问，申请维也纳大学，需要学士学位认证，想请教有经验的朋友，国内的学位具体怎么认证？
我已经在奥地利读了一个硕士学位，还需要在过APS审核吗？

下面是我在大学网页上看到的，1）教育部认证，2）外交部认证，3）使馆认证，4）还要APS
其中教育部认证是什么？有国内颁发的学历学位证书是不是就算是教育部认证了？
Please report to the Austrian embassy/consulate in the country where your documents were issued, showing your certificate. For your admission procedure, the last authentication issued by an Austrian authority is crucial.
Applicants with documents issued in China, who finished at least one semester of a study programme in China, have to present a certificate from the Academic Evaluation Centre (Akademische Prüfungsstelle - APS) of the German Embassy additionally to their legalised documents.


谢谢各位了！
